Magnetite and Biotite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Magnetite and Biotite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Magnetite Vs Biotite during the identification of gemstone. Specific gravity of Magnetite is whereas that of Biotite is .
